T o'alZ whom t may concern Be it knowntliat l, PrriLnIr A. WHITE,

acitizen of the United States, residingfat- 'to force one 'end of therim past the other "'the abutting ends of a split to reduce the diameterof the rim.

further object of mv invention is to `I oodiment shown in Figurey 2ofthe drawings;

provide an attachment for reducing the diameter cfa demountable splitrim'and adapted to maintain the rim'temporarily i inits reducedposition.

A further object of my invention is-toV provvide an attachment forreducing the diameter of a demountable'split rim and adapted easily to.force the rim from its reduced position back to normal position.

A further object ot my invention is'to provide an attachment for`'reducing the' diameter of a demountable split rim and adapted tosecure the abuttingr ends of 4the i rim against accldental movement fromtheir normal position. A

. A` further object of my invention istto provide a cover plate for thespace between demountable rim. f

` A filrtherobject of my` invention is to providea rim so constructed asto retain a vtire thereon 'securely againstnsidewise and creepingmovement and adapted easily to" be reduced in 'diamcterby forcingIoneend .past the other; y

Other objects of my'inventionwill be ap parent irom the followingdescription and from the accompanying drawings of. illustrativeembodiments thereof, in which- Figurell is a perspective of a tire'withf a split, demountable rim therein reduced in diameter 'by oneembodiment of the cattachment therefor;

Similar reference ,characters refer to similar .parts throughout .thedrawings. f

In the embodiment of Figures l, 2, 3, and

4.. of the drawings, referencecharacterl v indicates .the portion of a.split rim on one side..offandV adjacentfts transverse .cut or-split,reference character 2 the portion of therim on the other side ofand adjacent saidwcut orsplit, and reference character. 3 al, coverplate for the transverse out itself. Adjacent the end of prtion 2,which` preferably is depressed as indicated at 4, is

mounteda lever 5 having an extension 6 thereon. .A lever 7 mounted onportionl .of the rim forms with lever 5- a toggle adapted to be operatedby a handle 8.

When the `rim is' in normal position as disclosed in Flgure 2 of thedrawings, ex-

'tension 6. will fit inldepression 4?:` and the v l toggle and handlewill lie close to the rim.

between andnot ext ding beyond the usual/,f

spacmg beads 15 on, he bottom of the rim'.

The cut or split will be covered by cover plate 3, thus protecting theinner tube of the tire from contact therewith. The ends of the rim willbe locked together securely by projections 9 and 10 on the rim passingthrough corresponding openings 13, 11, yand 12 in lever and in handle 8.

When it is desired to reduce the diameter of the rim, handle 8 isoperated as indicated in Figures 3 and 4. This causes extension 6 onlever f3 to press against cover plate 3 secured on end portion l, thusforcing end 1 up and end 2 down so that. the continued operation ofhandle 8- will force one end past the other as indicated in Figures 3and 4 of the drawings. The movement is facilitated in its early stagesby the shape of spacing beads l5 on end portion 1 which are cut away asindicated at 16 to form an incline. When in reduced position, extension6 Will engage behind projection to hold the parts temporarily in reducedposition, the projection preferably engaging a notch 14 provided in theend of extension 6 for that purpose. lVhen it is desired to return theparts to normal position, a slight pressure on handle 8 o1 on one of theabutting rim parts will enable extension 6 to pass projection 9, thespringiness of the rim tending to move it. part way to normal position,the remainder of the distance being "attained by operation of handle 8.F'

In the embodiment of Figures 5, 6, and 7 ot' the drawings, referencecharacter 21 indicates the portion of a split rim on one side of andadjacent its transverse cutl or split, reference character 22 theportion of' the rim on the other side of and adjacent said cut or split,and reference character 23 a cover plate for the transverse out it-`self. End portion 22 preferably has secured underneath thereof anextension plate 24, adjacent the end of which is mounted a lever 25having an extension 26 thereon. A lever 27 mounted on portion 21 of therim forms with lever 25 a toggle adapted to be operated by a handle 28.yThen in reduced position, extension 26 will engage behind projection 32to hold the parts temporarily in reduced position, a slight pressure onhandle 28 or on one of the abutting rim parts enabling the extension topass the projet-tion for the rim to return to normal posifion. When therim is in normal position as disclosed in Figure 5, extension 26 willlie on plate 24 outside ithe end of the rim, the other parts lying closeto the rim and the split covered by cover plate 23. y l/Vhen the rim isin normal position, the ends are locked together by projections 29 ,and32 engaging openings 30 and-33 (Figurc 9) in handle 28. The operation isthe same as in Figures 1, 2, 3, and.4.

The embodiment of Figures 1, 2, 3, and 4 differs principally from theembodiment of Figures 5, 6, and 7 in Weight and Width,

the former being' adapted for light, narrow rims and the latter forheavy, Wide rims. Figures 8 and 9 represent a difference inconstruction, the handle 28, as shown in Figure 9, being Wide enough topermit a cut-out portion 31 in which fits lever 25 and extension plate24. 1n both embodiments, the parts are so proportionedwas to utilize thebenefits of leverage in decreasing the diameter of the rim so that an.excessive amount of force is not necessary even for heavy rims.

When rims of the type disclosed are used for pneumatic tires it isnecessary to have flanges to hold the tire in place. lf unitary flangesof the necessary height are used it is difficult to force one end of therim pastthe other to decrease the diameter of the rim to the sizedesired, asv the bending is in the plane of the flanges. lff loose ringsare used with a low, integral fiange, the rings are difficult to handleWhen changing tires and the tire is liable to creep on the rim with the'rings and cut the valve stem. ln order to obviate these difficulties, ashort flangeand ring construction may be used as shown in Figures 10,ll` and 12 of the drawings. In this construction, 'arim 4() is shoivnwith low, unitary flanges` 4l and 42 and With rings 43 and 44.

One of these rings, as ring 43 (Figures 10 and 12)', is securedpreferably permanently and in any desired manner as by rivets 45 to theportion of the rim adjacent its split and on only one side thereof forapproximately one-third of the distance around the rim. The shortdistance the ring is secured to the rim Will not interfere materiallywith the resistance of the rim to bending and yet it has all theadvantages of a unitary flange of the Same height. Figure 10 of thedrawings shows the rim reduced in diameter with the ring 43 secured toflange 41 in the manner described.

The other-ring, as ring 44 (Figures l1 and 12), is removable from therim when the u1- ameter of the rim is reduced in order to change tires,but to prevent the tire and ring from creeping on the rim, ring 44 isprovided with any desired number of keys 46 adapted to fit incorresponding notches 47 on unitary` low flange 42 Whenfthe parts are innormal position.

The rim construction described thus combines the advantages of the fixedflange and the loose ring construction Without the disadvantagescommonly flowing from the use of either construction.

Many modifications of my invention will be apparent to those skilled inthe art withoutdeparting therefrom or from the scope of the claims, myinventio'n not being limited v to the particular embodiments thereofchosen for purposes of illustration, but comlll prising a rim adapted tobe decreased in size by forcing the abutting end portions rpast eachother into a superimposed position by mea.n' s of' members lying closely-adjacent the rim when in normal position,` utilizing thefbeneiits ofleverage to render the "operation easy, and comprising a rim easilydecreased in size and adapted to maintain a tire `thereon -Withoutsidewise or creeping movement. i AVhat I claim and desire to protect byLetters Patent is: :i i
